Evidence for sterile neutrinos at the eV-scale has been reported by several experiments starting with LSND in the late 1990s. A renaissance of reactor neutrino experiments around 2010 led to the very precise measurement of one of the mixing parameters, θ₁₃ -- in the run-up to this measurement flux calculations from the 1980's were scrutinized and surprisingly the flux was found to be higher than previously expected, leading to the so-called reactor anomaly. The reactor anomaly points to a sterile neutrino approximately compatible with the LSND result. We will review the evidence for and against sterile neutrinos at the eV-scale and provide an overview of the possible experimental tests of this hypothesis.
